Possible, but seems unlikely. In Bozen they mass-tested 65% of the population over the course of 3 days. They were getting 540 positive PCR tests every 100k people a week in the week before the mass screening; the latter yielded 900 positive antigen results every 100k people; they got 435 positive PCR tests every 100k people in the week after the screening. This 20% reduction in positive PCR tests seems mostly due to the lockdown, given that the week before the mass screening the reduction had been even greater, 32%.
